Title: A method for the production of bar spacers for use in reinforced concrete structures
Inventor: DALE OLAV
IPC: E04C5/20
Filed: 1969-07-01
Abstract: 1276874 Making reinforcement spacers O DALE and V J WRIGHT 1 July 1969 33199/ 69 Heading E1W A method of producing bar-spacers for reinforced concrete structures is characterised by providing holes 3 in a tube or pipe 1 of a rigid plastics material and then cutting the tube at an angle of 90‹ to the tube's length with the cutting line running across the said holes thereby forming short lengths of tube which at both ends have open parts of the said holes each constituting a bar-spacer. The drilling or punching of the holes as well as the cutting is done automatically as the tube is extruded or alternatively at a later date. Adjacent holes are positioned at right angles to each other and oval or key-hole shaped holes are punched to provide spacers having a snap-on action (Fig. 2). By cutting through a hole off-centre snap-on spacers as shown in Fig. 4 are produced. The tubes may be of square cross-section having longitudinal stiffeners or built-in reinforcements for heavy loading. (For Figures see next column)

Title: Improvements in or relating to the manufacture of permanent magnets
Inventor: BROWN KENNETH WILFRID
IPC: H01F1/06
Filed: 1953-12-02
Abstract: 758,021. Magnetic structures. GENERAL ELECTRIC CO., Ltd. Nov. 22, 1954 [Dec. 2, 1953], No. 33523/53. Class 38 (2). In making a permanent magnet by consolidating magnetic metallic powder having grains of colloidal dimensions, the grains are coated with an organic protective medium by immersion in a solution of the medium followed by evaporation of the solvent, the powder is compressed to a compact, and the compact is heated in a non-oxidizing atmosphere to remove the medium. The difficulties resulting from the powder being pyrophoric are thus avoided. The powder is of one or more of the metals iron, cobalt and nickel with, if desired, small additions of other materials. The specified protective media are oleates of metals such as lead and iron and naphthenates of metals such as iron, cobalt and lead, in the proportions of 0.5 to 8 per cent by weight. Suitable solvents are benzene and acetone. The compact may be compressed after as well as before the heating which may comprise a number of steps at different temperatures. The heating may remove all or not quite all of the protective medium according to the properties desired. Superficial oxidation of the compact and development of pyrophoricity can be prevented by a final impregnation with tung oil. In one example a cobalt iron powder obtained by the decomposition of mixed crystals of iron and cobalt formates is coated with 4 per cent of lead oleate in benzene was, when dry, compressed at 30 tons/sq. in. and heated first at 300‹ C. and then at 350‹ C. in hydrogen. Alternatively the medium was lead naphthenate in acetone. the pressure 50 tons/sq. in., and the heating at 150‹ and 350‹ C. A final pressure of 100 tons/sq. in. may be applied. Specification 590,392 is referred to.

Title: Improvements in or relating to electric switching circuits

Filed: 1960-09-30
Abstract: 912,163. Transistor switching circuits; amplitude modulating and demodulating systems. SMITH & SONS (ENGLAND) Ltd., S. Sept. 22, 1961 [Sept. 30, 1960], No. 33743/60. Classes 40 (5) and 40 (6). [Also in Group XL (b)] A switching circuit includes a symmetrical junction transistor of the kind in which when the collector-base and emitter-base junctions are both forward biased the emitter-collector potential does not exceed 5 mv., and is arranged such that any base current flowing in the absence of a signal divides itself equally between the collector-emitter electrodes. In a first embodiment, Fig. 2, the circuit between a source 5, e.g. a thermocouple, and a meter 6 is completed by the emitter collector path of a symmetrical transistor 1. A switching signal is connected between the terminals 3, and the resistors 4 are adjusted so that the base current divides equally between the emitter and collector. In a modification. Fig. 3 (not shown) two such switching circuits are used to connect either of two thermocouples to a meter common to both circuits. In a second embodiment, Fig. 7, a signal source is connected to a load via a circuit including series transistor 41 and shunt transistor 42, the two transistors being of opposite conductivity types. In order to complete the circuit, the switching signal 47 is arranged to switch transistor 41 on and transistor 42 off. The two transistors may be made the same conductivity type, antiphase switching signals being then used, Fig. 8 (not shown). One or other of the two transistors may be omitted, Figs. 5, 6 (not shown). In the case of the shunt transistor being omitted, a third winding may be provided on one of the transformers which is short-circuited by a further transistor when the switching circuit is open, to give a low output impedance. A number of such circuits may be switched either to a common load, or to individual loads by a common switching circuit. Fig. 9 (not shown). In a balanced modulator or demodulator, Fig. 10, two symmetrical transistors 66, 67 are alternatively switched to their conducting state by signals applied between terminals 69, and 71. These switching signals may be derived from a square wave generator 72, Fig. 10a, feeding a transformer having two output windings 75, 76 from which the antiphase signals are derived. Two Zener diodes 77 may be connected back-toback across the transformer input as a limiter.

To accurately size or condition the outer surfaces on preformed glass bodies such as conical ends 9 of glass tubes, the end 9 is inserted so that its outer surface is in contact with the moulding surface of a metal mould 1 and together they are cooled from a temperature between the transformation and working ranges of the glass to a temperature within or below the transformation range. As shown, the mould 1 is formed as an extension of a tube 2 secured to a base plate 3 over a corresponding aperture. The mould 1 is uniformly heated by a coil 4, but non-regular heating such as a single coil may be used where a stress zone is to be produced, e.g. as at a predetermined breaking point. A heat probe 6 is positioned to check the temperature of the mould, and may be used for automatic control of the operations. To accelerate cooling, an annular duct 7 has openings for directing air on to the mould and additional cooling air may be introduced through the base plate 3 for hollow open-ended bodies. Specification 1,063,467 is disclaimed.
